The two-parameter gamma distribution can be generalized by introducing a third parameter g, called a threshold or location parameter: replace x in (4.8) by x - g and This amounts to shifting the density curves in Figure 4.27 so that they begin their ascent or descent at g rather than 0. The article "Bivariate Flood Frequency Analysis with Historical Information Based on Copulas" (J. of Hydrologic Engr., 2013: 1018-1030) employs this distribution to model X = 3-day flood volume (108 m3 ). Suppose that values of the (very close to estimates in the cited article based on past data).
a. What are the mean value and standard deviation of X?
b. What is the probability that flood volume is between 100 and 150?
c. What is the probability that flood volume exceeds its mean value by more than one standard deviation?
d. What is the 95th percentile of the flood volume distribution?
In drawing an inference using a single mean in hypothesis testing, you often have a choice between doing a z-test or a t-test. Many researchers will always choose to do the t-test even under circumstances where the z-test would work as well.

How would you choose an appropriate level of significance for your statistical test? What are the possible outcomes and limitations of your statistical test?
When nicotine is absorbed by the body, cotinine is produced. A measurement of cotinine in the body is therefore a good indicator of how much a person smokes. How would you measure the cotinine level in the body
